How to define where control files are placed? [message #55896]

Hi,

I need to install two instances on the same machine under the same user. The problem I am having right now is that I cannot figure out how I specify where my control files are placed per instance!

For example, when I create a new instance, first I do:
startup NOMOUNT pfile="/a/b/c/d/inst1/pfile/initInst1.ora"

then I call create database... But then, my control ora_control1 ora_control2 are stored under $ORACLE_HOME/dbs
I want to have ora_control files under the directory that I specify and not default. How do I do it?

Also, how can I make Oracle remember which pfile is where for what instance? I mean is there a way I can do startup WITHOUT pfile=/xxxxx ?

Any script would be greatly appreciated!
Thanks,
Vic

Ok, I got the first one: I can specify the path in init.ora ... But still, how can I make ORacle remember which pfile is what instance?

by default ORACLE standards,
u are supposed to create an init parameter file (pfile)
in format of
init< yoursid >.ora
say ur ORACLE_SID=prod8i
then
ur init file should be named as initprod8i.ora and should be placed in $ORACLE_HOME/dbs (defualt oracle installations create a softlink for this file in $ORACLE_BASE/admin/< sid >/pfile directory).
if all these are properly configured.
and ORACLE_SID and ORACLE_HOME is properly set,
login into svrmgrl , connect as internal.
just issue comand startup .
it will by default start ur init< $ORACLE_SID >.ora file.

that is why u export the ORACLE_SID( to startup / shutdown an individual database).
if u have mutliple ORACLE_SID in multiple homes,
and u want one dbstart script to handle (startup/shutdown) all the instances
use the /etc/oratab file.
